    Perfect Craftsmanship and excellent customer service!! Ordered the washer fluid reservoir and coolant tank reservoir and was blown away by the craftsmanship Spencer puts into his products! Had an issue with the fitment of the coolant reservoir for my early 88 silverado and after sending some pics and measurements to him he made a new reservoir and it fit perfectly! Would recommend Kloc Fabrication to anyone wanting a custom part made for their vehicle!

    Coolant & breather/catch can tank!

    Tank design and setup are perfect! Fits great with the A/C accumulator next to it, I used -10an 45 degree fittings, just have to be sure to clock ac hose correctly.
    Fits, functions, looks beautiful! Highly recommend all Kloc fab parts!

    Custom Coolant Tank and Washer Resevoir

    I've had two tanks made from him so far and quality is top notch. The second he made from a template and some measurements I gave him and it came out perfect.
